Specilicatinn forming part of Letters Patent No. llqli, dated December29, 1874; application tiled December l2, 1874.

To all whom it may concern:

Be it known that I, UHARLEs E. ROBINSON, of the city oi' Brooklyn, inthe county of Kings and State otlNew York, have invented an lmprovedAtomizer, oi'- which the following is a speeiiication:

My invention consists in the construction and combination ofthe liquidor oii valve and the gas or steam valve in an atomizer iu such a mannerthat, while the steam-valve surrounds the oil-valve, both may beadjusted independent of each. other, to regulate the quantitativeproportion of the oil and steam jets, the outer valve being so ar1anged, with respect to the valve-seat, that the oil and steam, inissuing from their respective valves, will form jets ot' the shape ot'thin, hollow cones inverted toward each other and intersecting eachother, thereby insuring their thorough mixture and atomization. ltfurther consists in the combination ot' the valves with the induction-pipes, and also the adjustment for the valves, as will behereinafter described with reference to the accompanying drawing, inwhich- Figure l is a longitudinal section of an atomizer constructedaccording to my present invention. Fig. 2 is a detail section of thcburner, taken through the line c .c oi' Fig'. l. Fi 3 is a cross-sectiontaken through the line y 1/ ot' l. Figs. Il and 5 are end views ot' thestuffing-boxes t'or the steam and oil valves, respectively. Fig. (i is adetail longitudinal section ot' oil-valve stem and stuiiing-box. Fig. 7is a detail section of a n'iodiiication ot` the burner. Fig. 8 is asection of the same taken through the line e c of Fig. 7.

Similar letters ot reference indicate corresponding parts in the severalfigures.

A is a tube closed in one end, and there provided with the stuffing-boxB for tightening around the stein oi" the steam valve, which, at or nearthe other end, is guided in a bridge-piece, a', formed in or attached tothe tube A. O is the steam-valve, consisting ot' a tube, one end ofwhich is turned conical outside to form the steam-valve surface proper,and also conical inside to form the seat for the oil-valve. Dis a shorttube joining' by screw-threads .the tube A to the burner. ln

this tube D is provided the seat d1 for the valve U, and also abridge-mecc, d", for guiding the elongated stem ot' the oil-valve. rllhestem of the steam-valve O is threaded, at c, on the outside a distancefrom its outer end i'or the reception of a hand-nut, E, provided with acircular iiange, c', which revolves in lugs b formed on the stutiing-boxB. The hand-nut L being thus held in position onto the smiling-box B, aturning' of the same on the threads ofthe valve-stem C will cause thelatter to slide back or forth, as the case may be, thereby regulatingthe size of the steamvalve opening at d1, and consequently the quantityot' steam required to atomize the oil. F is the oil valve and stemWorking inside of the steam valve and stem C. Itis threaded at f adistance from its outer end, and regulated by the hand-nut G, having acircular flange, g', revolving in lugs or cleats, h', on thestorting-box H in a manner exactly simila-r to that above described or'regulating the steam-valve U. To prevent the stem ot the oil-valve Ffrom turning' with the nut, (whereby the necessary sliding motion wouldbe defeated) a key, I, is fastened in the stuffing'- box H, and tits ina groove provided iu the end j" ot' the valve-stein F. The stuffing-boxH is secured at the end of a T-joint, J, forming an elongation to thepipe C, to which it is united by an ordinary pipe titting,j. K is theoil-supply pipe, and L the steam-supply pipe. For heating the oil, itspipe K is carried for some distance inside ot' the steam-pi pe L untilit branches oit' to the T-joint J and atomizer, the steampipe L being'secured by coupling to the tube A, and the oil-pipe K being secured aswell to the pipe L as to the T-joint J', and the latter being' firmlysecured to the valve-stem C. rlhis last is therefore prevented fromturning with the hand-nut E, while the distance, from the atomizer tothe portion ot' the steam-pipe parallel thereto, is made sutiicientl ylarge to allow them to spring and yield so as not to interfere with thesliding' motion ofthe valve U when being adjusted. The passage of thesteam is indicated on the drawing by arrows l, and that ot the oil byarrows 2. The oil being forced in by steam-pressure from a separatesteam-pipe, and the valve- Q ramene openings at F C d1 being of theshape of two hollow cones inverted toward each other, the jets of oiland steam must assume the shape corresponding, and, intersecting eachother, become most thoroughly atomized and mixed before entering theburner. M is the burner, made, preferably, of the shape shown in thedrawing.

In order to secure the most economical and effective combustion of theatomized oil and steam for fuel in a furnace, I construct the openingsin the burner as follows: I make a line slit or cut, mf, eitherlengthwise, as shown in Figs. I and 2, or crosswise, as shown in Figs. 7and 8, and not quite through the thickness of the metal in the burner M.In the bottom of the cut m I then make one or more very small holes, n.By now closing the slits partially, so that the thickness of the cutwill be less than the diameter of the holes u, the gas-jets issuingthrough the holes a will be flattened out and spread in the slits m',leaving the burner as thin flames of intense heat.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. In an atomizer, the combination of a valve-seat, d1, and the valves FC, one placed inside of the other, and both adjustable by means of thehand-nuts E G, in the manner substantially as specified.

2. The combination of the valve F, the tubular valve C, the Valve-seat,and the pipes A, L, and K, substantially as and for the purposedescribed. v

3. The combination of the stuffing-box H, having lugs h', with the keyI, valve-stem j", and hand-nut Gr, substantially as and for the purposedescribed.
